TC Injection Electrodes (CU)

The ultimate in functionality, precision, and control, the Cosman UnifiedTM (CU) is a sterile-packed, tissue-piercing RF cannula/electrode with a long fluid injection line and thermocouple (TC) temperature sensor. The CU simplifies RF procedures, inventory control, and sterilization logistics. Its fluid line helps maintain electrode position during injection to optimize control of lesion position and size. Its unique design is protected by U.S. Patent 7,862,563.

Each Cosman Unified electrode comes sterile-packed in a variety of sizes with sharp tissue-piecing tips for targeting nerves in different parts of the spine and body:

23, 22, 20 gauge

5, 10 mm tip length

6, 10, 15 cm shaft length

straight or curved

echogenic or standard

The CU Simplifies RF Procedures and Improves Precision

In classical RF practice, the RF cannula is electrified using a separate RF electrode, and numerous manipulations are required to both inject anesthetic and lesion a nerve. Today, the new Cosman CUTM injection electrode unifies a cannula, electrode, and flexible injection port into a single tissue-piercing, temperature-measuring device. Since the CU electrode does not need to be manipulated through stimulation, injection, and ablation, you can ensure that the electrode doesn’t shift from its intended position.
